Model United Nations, also known as Model UN or MUN, is an extra-curricular activity in which students role-play delegates to the United Nations and simulate UN councils or General Assembly committees. Every delegate is assigned a country, organization or NGO, the policy and political stand of which he or she will have to correctly and effectively portray during the conference. MUN conferences are organized by a high school or college MUN club. At the end of most conferences, outstanding delegates in each committee are recognized and given an award certificate; the Best Delegate in each committee, however, receives a medal. Tens of thousands of high school and college students across the world participate in MUNs, which involves substantial researching, public speaking, debating, and writing skills, as well as critical thinking, teamwork, and leadership abilities.
